A new solar coupling regeneration system used in the desiccant air-conditioning system is proposed in order to improve the reliability of solar desiccant regeneration system. Analysis of the method of the new system was made and the energy model of the new system was developed. Moreover, the performance of the new system was compared with the solar thermal regeneration system. The results show that the solar coupling regeneration system is more energy efficient than the solar thermal regeneration system under both operational conditions. Under operational condition 1, the most influential factor of the solar coupling regeneration system is the concentration of desiccant at the exit of the solar collector/regenerator, and it should be maintained as low as possible. Moreover, the regeneration efficiency of the solar collector/regenerator affects the regeneration performance of the solar coupling regeneration system greatly.
